WEATHER-STRIPPING.

Patented Oct. 26, 1915.

Application led January 16, 1915. Serial No. 2,610.

To all whom t may concern:

Be it known that I, DANIEL HoY'r, a citizen of the United States, residing at East Orange, Essex county, State of New Jersey, have'invented certain new and useful Improvements in Weather-Stripping; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to weather stripping means for sealing the side edges of windows and particularly car windows Where the cars are constructed of steel and where it is difficult to secure any kind of device to the metallic window frames.

The window frames of the ordinary steel car have metallic side posts to which the outside sash stops are permanently riveted. The inside stops and curtain fixture grooves are usually formed together from asingle sheet of metal and are secured to the metallic posts of the window frame with machine screws, and stops are secured to the posts absolutely parallel to the outside stops leaving a space, or sash guideway, therebetween, of somewhat greater width than the thickness of the sash. The side posts, while supposed to be, parallel to each other, are found to vary somewhat. With these permanent,

yunchangeable conditions of the window frame and sash stops, it has been found difficult to prevent the sash from rattling, to stop the passage of air and dust, and to prevent cinders and grit from accumulating in the sash guideways which prevent the proper operation of the sash.

One of the objects of this invention is to so equip a car window sash that it will be air, dust and cinder proof, and yet allow the sash to be readily raised or lowered.

Another object is to make a weather strip which may be readily applied to the fiat side edges of a window sash without cutting or grooving and which any ordinary workman can apply without special tools or machinery.

Another object is to make a weather strip partly of felt so that the edges only will contact with the 'inside' and outside sash stops, also to provide means to prevent the felt contacting the faces of the window posts.

Another object is to equip a sash so that the side edges are weather proof and at the same time are held resiliently between the window posts.

The invention consists of a device as hereinafter described and illustrated in the accompanying drawings, in which:

Figure l illustrates a broken portion of a window frame and a sash equipped with the preferred construction of my novel weather strip, the inside sash stops being broken away showing one edge of the felt as it bears on the sash stop, also showing a portion of the guide springs and plates as they bear against the posts of the window frame. rllhe felt is also broken away at one place showing the binders which hold the felt. Fig. 2 shows a cross sectional view of Fig. 1 taken on the lline 2 2. Fig. 3 shows a cross sectional view of Fig. l taken on the line 3*-3. Fig. 4: shows a. detail face view of my novel weather strip equipped with spring guides. Fig. 5 is an edge view of Fig. 4. Fig. 6 shows a detail face view of the weather strip having solid guide plates'. Fig. 7 is an edge view of Fig. 6. Fig. 8 is a cross sectional view of one side of a sash with a modified form of the weather strip applied to the sash before the latter is installed in the window frame. Fig. 9 is a view similar to Fig. l, but showing ymy improvement utilized in connection with guide plates alone at Ieach side edge of the sash. Fig. 10 is a broken section at the line 10-10 of Fig. 6, and Fig. 11 a broken section at the line 11-11 of Fig. 4.

Similar numerals of reference denote like parts in the several figures of the drawing.

Referring'to the drawings, l is the win-v and of a width somewhat wider than thedistance between the inside sash stop 4 and the outside sash stop 5, the length to be the full length of the sash 3. The felt is secured between the two metallic binders and 7, the edge S of the felt extending considerably more over the edge of the binders 6 and 7 than the edge'9.

In applying the strips to the flat side edges of the sash, the metallic binders G and 7 are designed to be secured central of the side edges of the sash 3, so that the edge of" the felt 9 will be approximately even with the o-utside face of the sash, or it may extend slightly beyond. The inside edge of the felt 8 extends a considerable distance beyond the inside face of the sash. It will be understood that each side edge of the sash is equipped-with one of these weather strips.

On the outside of the binder 7 I secure a series of two or more fiat bow springs 10, and these springs may be on both side edges of the sash. or. l can locate them on one side edge and equip the other side edge with two or more solid guide plates 14, as shown at Fig. 1. But this is a very ilnmaterial matter and has nothing to do with the weather stripping proper, and, in cheap structures, I can omit the springs altogether, and secure solid guide strips 1I to both side edges of the sash, as shown at Fig. 9. The sash is then placed in the window frame between the posts, the inside stops being removed, and in placing the sash in the window frame the springs are compressed and bear on the faces of the posts holdingthe sash resiliently between the posts. The sash is then carried back against the outside stops, and the inside `stops are placed lagainst the extended portion of the felt S and forced back to their position on the post and secured there by means of the screws 15 driven into their previously prepared screw holes. In forcing the inside stops 4 back against the felt vedge 8 the out-side face of the sash 3 and the felt edge 9 are pressed together against the outside stop 5, thus :making practically a. packed joint between the inside and outside sash stops. It will be readily seen that, no matter how poorly the sash itself tits in the guideways, either edgewise or sidewise` my improvement attached. tothe side edges of the sash will render the latter perfectly air tight, will prevent all rattle, and allow the sash to be operated freely.

It will be noted, by referring to Figs. 2

and 3, that the binders 6 and 7 are of a width considerably less than the thickness of t-he sash, thus leaving recesses 11 and 12 at each side of the felt and between the edges of the binders 6 and 7 and the stops f4 and 5,the use and necessity of which recesses I Will now describe.

In forcing the inside stop in position, the felt edge 8 is compressed, and this material', like all other material of an elastic nature, when lpressed one Way must go, another Way, and the recesses 1l and 12 are provided to allow room for the telt to go sidewise when compressed edgewise. and the felt being of an elastic nature tends to resume its former normal shape making a constant pressure on the parallel stops t and If, in the course of time. the felt becomes set in its compressed position. it will still make a perfect molded tit between the inside and outside sash stops, and wear on the edges of the felt against the smooth surfaces of the stops Je and 5 would be infinitesimal. Also, these spaces 1l and 12 provide pockets extending the entire length of the sash, and if any particles of dirt should work their way into these pockets. such dirt would be deposited on the window sill and could never work its way through the outside and inside felt and into the car.

`When solid guide plates 14 are employed they may be made integral with the outer binders 7, if desired. the function of these plates being to prevent the felt from hearing against the rough faces ot the posts. Also, the side edges of the sash throughout their length may be so constructed as to form an integral tongue 16 to take the place of the binder G, as shown at Fig. 8 and. I therefore do not wish to be limited in this respect.

While I have used the word felt throughout this specification, I want it to be understood that in the place of felt any material of similar nature may be used.

Having thus described my invention what l claim as new and desire to secure bv Letters Patent is 1. The combination of a window frame, said frame having side posts carrying inside and outside sash stops forming guideways for a sash, a sash of less thickness than the width of said guideways and adapted to move therein, a` weather strip secured to each side edge of said sash comprising a strip of thick feltniade wider than the guideways. said felt having a free edge at each side thereof, one edge adapted to bear against the inside stop and the other edge adapted to bear against the outside stop, the free edges of the felt being compressed between the stops, recesses formed at the sides of the free edges of the felt whereby the felt may have space to expand sidewise into the recesses when conipressed edgewise by the stops and thereby prevent the felt from becoming interposed between the faces of the sash and the stops.

2. The combination of a window frame, said frame having side posts carrying inside and outside sash stops forming guideways, a sash adapted to move in the guideways, and a weather strip secured to each side edge of the. sash, said weather strip comprising a strip of thick felt wider than the guideways, one edge of the felt extending slightly beyond the outside face of the sash and the other edge of the felt extending a much greater dista-nce beyond the inside face of the sash, the arrangement being such that when the felt is compressed between the stops the force will carry the sash laterally against the outside stops and leave :L space between the sash and inside stops.

In testimony whereof aix my signature in presence of two Witnesses.
